Title: Color reader
Inventor: NAGANO BUNICHI
IPC: H04N1/04
Filed: 1984-11-16
Abstract: PURPOSE:To equal the AD conversion accuracy and to improve the accuracy of color reading by equaling output levels of CCD sensors corresponding to light emitting energies of red, green and blue fluorescent lamps. CONSTITUTION:Integrating periods PR, PG and PB of red, green and blue reflected light energies are decided, and shading waveform data is written in R, G and B memories 16-18. Lamps continue flickering for a several or several-ten sec. Then, after red, green and blue light emitting periods are detected and a shading memory 15 is refreshed, an operation enters a color reading action. In order to weaken a red color, its light emitting period is again decided, however, re-writing to the R memory 16 is not executed. Based on the light emitting period decided in such a way the color reading is executed. In order to emphasize a red color, its light emitting period is decided, and the color reading is executed.

Title: Hermitically sealing/fixing device of exchah geable member
Inventor: SHIYARURU GURASHIE
IPC: G21F7/053
Filed: 1990-09-14
Abstract: PURPOSE: To arrange an interchangeable member in an accurate angular position in relation to a cell flange by providing a means for immobilizing a safety ring rotated in relation to the flange and a support ring infixing the safety ring by a bayonet ring. CONSTITUTION: A safety ring 72 is fixed to a cell flange 16 and a support ring 36 simultaneously through the cooperation of parts 24, 74 of a bayonet ring device formed between the cell flange 16 and the safety ring 72 and through the cooperation of parts 68, 76 formed between the support ring 36 and the safety ring 72. Levers 88, 82 and a snug 78 take operating positions as shown in a figure. Entering a groove 34, the lever 82 immobilizes the safety ring 72 rotated inside the cell flange 16. At the same time, the snug 78 immobilizes the support ring 36 rotated in relation to the safety ring 72. The angular position of the support ring 36 in the cell flange can therefore be accurately guaranteed without the danger of accidental tripping.

Title: Ceramic film for endothermic reaction
Inventor: PRASAD RAVI
IPC: B01J8/06
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for generating a synthetic gas having a high H2/CO molar ratio and a reactor. SOLUTION: A H2/CO ratio of a synthetic gas (mixture of hydrogen and carbon monoxide) is maintained to about 3. The synthetic gas having the molar ratio is obtained by the steam reforming reaction executed according to the chemical equation of CH4+H2O→3H2+CO. A low grade fuel is burnt in the reactor to obtain heat required for the endothermic steam reforming reaction and the heat of combustion is transferred to the endothermic steam reforming reaction. The generation of undesirable NOx is minimized by using an oxygen selective ion transferring film element 18 to transfer oxygen required for the combustion.

Title: Current applying electrode plate
Inventor: MOGI KANJI
IPC: H05F1/02
Filed: 1995-09-21
Abstract: PURPOSE: To prevent the retention of the electric charge positively responsible for an electric shock, even in a case where the insulating covering member having a required volume resistivity value is used, by attaching a conductive member to the entire surface of the insulating covering member. CONSTITUTION: Since a conductive member 10A is attached to the entire surfaces of both resin sheets 10B and 10C forming an insulating covering member with an adhesive agent, the conductive member 10A and the resin sheets 10B and 10C are maintained in close contact over a long period of time without forming any gap therebetween. Therefore, even if the resin sheets 10B and 10C having the volume resistivity value which allows charge transfer in a very small amount are used, on charge retention takes place on the applying side in the resin sheets 10B and 10C and, therefore, the occurrence of the electric shock due to the charge retention can be prevented.

Title: Motor speed controller
Inventor: YAMAGUCHI OSAMU
IPC: H02P29/00
Filed: 1991-09-24
Abstract: PURPOSE:To remarkably improve the controlling characteristic of a motor speed controller by eliminating the occurrence of a time lag when the rotating speed of a motor is changed. CONSTITUTION:The value corresponding to the torque required for accelerating or decelerating a motor 5 is found by differentiating the output of a speed command generation means 1 by means of a differentiation means 7. Since the torque required for accelerating or decelerating the motor 5 can be generated without relying on a feedback loop by adding the output of a comparison means 3 to the found result in a feed-forward state by using an addition means 8 at the input section of a motor drive circuit 4, the controlling characteristic of this motor speed controller can be remarkably improved.

Filed: 1984-11-21
Abstract: PURPOSE:To obtain easily superfine granular alpha-alumina without the growth of single crystal particles by heating and calcining the crushed diaspore material to change it into alpha-alumina. CONSTITUTION:The diaspore material crushed in the required granule size is heated and calcined to change it into alpha-alumina. As the disapore material to be used, either diaspore synthesized by the hydrothermal reaction wherein the alumina-contg. substance such as gibbsite is used as raw material or the natural one consisting essentially of diapore as the mineral component is adopted. As the granule size wherein the diapoer material is crushed into the ultrafine granule, it may be crushed so that the granule size of ultrafine granular alpha-alumina as a product is regulated to the required granule and normally it is preferably crushed so taht the average granule size of 50wt% by a settling method is made to <=1mu. As the crushing method, the wet crushing is preferable because the unpreferable chemical reaction due to the heat release in a crushing period can be avoided and the crushing efficiency in the ultrafine crushing is high.
